Wagenborg positions beams connecting residential towers

Wagenborg transported and positioned four enormous steel beams which connect the residential towers of the Pontsteiger in Amsterdam, the Netherlands.

The steel beams were manufactured by Almelo-based Buiting Staalbouw and they measured up to 48.5m long, 5m wide, 9.4m high and weighed up to 78t.

Wagenborg transported the beams from the fabrication site in Almelo to CTT quay in the same city, where a mobile crane was used to move them onto an inland vessel. Then they were transported to Amsterdam via water.

At the Pontsteiger site, the company deployed two 500t AC 500, both equipped with jib, to position the beams. Due to space limitations, the all terrain cranes were parked between the building and the sheet piling.

While positioning the beams, craftsmanship and communication between the crane operators was paramount, considering that the margin to manoeuvre was only millimeters

The Pontsteiger, designed by architectural firm Arons & Gelauff, will be one of Amsterdam’s largest and tallest residential buildings.
